Solve each system of equations by graphing.
y=x-2
y=3x-8

Step 1. Graphing the system of equations is

Step 2. Based on the graph, the intersection point is (3,1)

Step 3. Check if the intersection point (3,1) satisfies the system of equations

y=x-2 1=3-2 which is a true statement
y=3x-8 1=3*3-8 which is another true statement

Step 4. ANSWER: The solution is (3,1) or x=3 and y=1.

I hope the above steps were helpful.
